saved lives. he was entering the building, again, with a handgun and certainly his intent had been shown he wanted to harm the people. certainly, if they would not have done that, he would have killed or injured other people. >> reporter: now, as you heard there, what we know from police is this gunman entered the meeting with what is described as a long gun. then, apparently emptied it, then went back out to his car to get a handgun. that's when he was tackled to the ground. he was prevented from shooting other people. three people are dead. at least two more in the hospital at this hour. >> any details on the shooter, a motive, perhaps? >> reporter: that's a big question. i can tell you what we know so far. police identified the main suspect. he is from here. he is from this town.
